Updates since the article was written

The biggest improvement appears to be that appears the "breakaround" is no longer required! libloading seems to have made some changes (including declaring Library::new as unsafe) that properly closes the lib on drop. I've tested it with valgrind to confirm that the memory leaks have disappeared, and couldn't find any issues.

Other nice updates include:

• notify has an easier to use api
• the target folder has a ./deps folder you can check for write events to, this means you can just watch the lib folder and rebuild the main folder. i.e

# from ./libgreet
cargo-watch -- cargo build --manifest-path=../Cargo.toml

The article is a really great read and there is a lot to learn from it.
